OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 453,35*?, dated J'une-2, 1891.

Application filed March 19,1889. Serial No. 303,896. (No model.)Patented in England January 14, 1887, No. 610.

A.To all whom it may concern,.-

Be it known that I, J AMES LYLE, a subject of the Queen of Great Britainand Ireland, and aresident of Paisley, Renfrewshire, Scotland, haveinvented certain Improved Appliances for Burning Oils, (for which apatent has been obtained in Great Britain, No. 610, dated January 14,1887,) of which the follow- 1n g 1s a specification.

This invention consists of improvements in the construction of burnersor jet-nozzles for the burning of mineral or other oils for lighting andheating purposes, and in which either compressed air or a steam-j et ismade to unite and burn with theoil-jet in or at the point of theseimproved-nozzle burners, so as to cause perfect combustion.

In the accompanying drawings, Figures l and 2 show a sectional elevationand a sectional plan, the plan being taken on the'line l 1 of Fig. l,respectively, of my burner and its ttings for lighting purposes. Figs. 3and et show a Vertical section and half-sectional plan, respectively, atright angles to each other, of a horizontal arrangement of burner anditsl fittings, as more particularly suited and designed for-heatingpurposes and blowing the llame into furnaces. Fig. 5 shows a detachedside elevation of the annular oil and air burner and internal regulatingand cleaning spindle.

The burner shown in Figs. l and 2 consists of the hollow cylindricaloil-tube A A', concentrically within an outer air or steam chamber andnozzle B B', both preferably with screwed neck and stop-joint collars attheir lower ends for being secured into their correspondinglyscrewedsockets. The central tube is screwed into the inner end of its lateraloil-supply branch A3while the outer tube B B is screwed into the socketB2 of its valved air-supply branch B3, so as to lead t-he supply ofcompressed air or steam (whichever is used) up the annular space bbetween the central tube A A and the outer tube B.

The upper part of the inner tube A is made with a'ring of holes a toemit a thin circular stream of oil out into a narrow annular space b,formed all round the outer circumference of the inner perforated nozzleA and the inner circumference of the contracted upper end B of the outerair-tube B. By this a hollow spray jet of oil and air or oil andvsuperheated steam (when that is used instead of the air) is produced,to be ignited and burned beyond the burner A B as indicated by thedotted dame-line a'.

The annular oil-nozzle A A is left open at the upper end, and has aregulating and cleaning spindle e, with a piston c at one end and ahandle e3 at the other, this spindle being screwed at e in astuffing-box socket A2. The piston e at the upper end, which fills theburner A A, occupies a position above the ring of oil-holes a in theburner-nozzle, so that when this spindle e c is screwed up or down itregulates the openings in the holes for the emission of the oil, and italso cleans out the oil-nozzle A A, its body part e being small enoughin diameter to allow the oil to pass up to, the burner from the socketand branch A3.

The coupling branches D and C are connected to the oil-supply AB and theair-supply B3, respectively, of the burner by the screwcoupling parts D3and C3, which latter are either made polygonal or are provided withcross-arms d cl3, respectively, for tightening up these parts.

Referring tol Figs. 3 and 4, this shows a simple arrangement of theburner A A and B B as mounted horizontally in the sockets A2 B2 of itsoil and air branches A3 B3, which latter B3 carries the whole on thecouplingbranch C', with jointing-nuts at C, of the air or steam pipe.(Not shown in these figures.) [n this construction there is a shortprojecting annular rim at b2, forming a continuation of the stein Bbeyond the burner B for protecting the annular flame-jet 2, formed atthe nozzle b. Otherwise this is substantially the same as shown in Figs.l and 2, and it is lettered to correspond.
